Clippers watch a lot of film in preparation for Cleveland

Before the Clippers participated in their shoot-around early Thursday afternoon, they watched a lot of film of their recent transgressions.

The purpose of the session was to try and identify why the Clippers have had so many hiccups in their last three losses and how those could be fixed before facing the defending NBA champion Cleveland Cavaliers that night at Quicken Loans Arena.

Defensively, the Clippers have allowed 108.6 points per game in their last three losses. They got down by 18 in the loss to Detroit, lost by 21 at Indiana and blew an 18-point lead at Brooklyn.

“We got to watch some film, go over some situations on some things we kind of made mistakes on, that we beat ourselves on,” DeAndre Jordan said. “It’s just things that aren’t what we were taught and gone through in training camp this year. We’ve just got to tweak some things. But it’s mainly focus.”

Jordan strongly suggested after the Brooklyn defeat that the Clippers were showing signs of being an overconfident group for no good reason.

He said that pervasive attitude has to stop immediately.

“I think that losing three in a row helps,” Jordan said. “I thought that losing two in a row would help. But I think that we’ve got to realize that we don’t get opportunities like this very often, if at all, throughout your career and we’ve got to take advantage of it. If you disrespect the game, you’re not going to win very many games at all.”

Jordan reflected on how the Clippers still “played the right way” in early-season losses at home to Oklahoma City and Memphis.

“But the last three losses that we’ve had, they’re not like builders,” Jordan said. “It’s kind of like we’re taking steps backwards. You can’t do that. You want to gradually get better as the season goes on and then reach your peak later on. But we haven’t done that in the past few games, so hopefully we can tonight kind of change that. But we had a long film session today, so we’ve seen it.”

Rivers hears from NBA

Upon getting ejected from the Brooklyn game for receiving two technical fouls in the first overtime of the loss, Clippers Coach Doc Rivers said he indeed had a conversation with the NBA league office about his behavior.

“Yeah, of course I have,” Rivers said. “What kind of question is that?”

Rivers wasn’t fined by the league.

There was 18.6 seconds left in the first overtime when Rivers was issued his first technical foul by referee Ken Mauer. Rivers was upset because he had been talking to referee Lauren Holtkamp when Mauer intervened.

Mauer then hit Rivers with a second technical foul, making his ejection automatic.

Rivers knew the talk would be about him exceeding the space of the coaching box.

He said it was a point of emphasis during the summer that coaches should not get out of the coaching box or risk getting a technical foul. Rivers was out of the coaching box against the Nets when he was whistled for the first technical foul.

“We’ve always laughed at the whole thing, honestly,” Rivers said. “There should be no box. There should be no nothing. You should be able to do what you want…. As long as you’re not obstructing the game or anything, I don’t think it looks bad. If I come across half court and I’m challenging a ref, the ref knows when to call a tech or not. You don’t need any rules for that. But it’s the rule.

“I can honestly tell you I’m not even sure where the coaching box is at,” Rivers continued. “So I’m going to have it marked up tonight so I can make sure I know. But I get the rule you can’t cross half court. Anyway.”
